Just create a data connection&nbsp;to retrieve data from the InfoPath Designer and give it the URL for the list but don&#39;t query on load. When they select the time slot, add a rule with two actions: set the query field and then query the data connection. Bind the dropdown to the data source that s returned. Should be straightforward.</p><p>Good luck!</p>InfoPath 2010 form to query SharePoint list for open rooms for given time slothttps://www.infopathdev.com:443/forums/thread/84400.aspxWed, 14 Nov 2012 11:49:53 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:84400SP Tom0https://www.infopathdev.com:443/forums/thread/84400.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=84400I have created a booking request form that submits the form to a SharePoint list and all of that works. What I need no to implement is when a user selects a time slot the next step is to query that SharePoint list and populate a list of available rooms for that open time slot. Example I pick November 14 10:00AM to 11:00AM then query the same SharePoint list for rooms available at that time and display in a drop down so a user can choose that open room. I appreciate any assistance.
